British No. 12 Richard Bloomfield continued his giant-killing form as he upset the odds to topple No. 2 seed Santiago Giraldo 6-3 7-5(5) at the Campbell's Hall of Fame Championship.

The 27-year-old qualifier from Norwich, who knocked out Christophe Rochus in the first round to claim his first win on the ATP Tour since beating Carlos Berlocq in the first round at Wimbledon in 2006, produced a stunning display of offensive hitting to seal an unlikely place in the quarter-finals by beating a player ranked 496 places above him in the world.

The world No. 552 served nine aces and secured two breaks of serve to seal his progress and will play Ryan Harrison in the next round after he overcame fellow American Denis Kudla in straight sets.

Jamaica's Dustin Brown continued the infamous 'Casino Curse' in Newport as he took out No. 1 seed and 2009 finalist Sam Querrey.

No top seed has won the title in the 35-year history of the tournament and Brown made sure that record would remain as he downed the world No. 19 6-4 6-3 in a mere 47 minutes. Querrey, who beat world No. 4 Andy Murray en route to winning the AEGON Championships at The Queen's Club last month, failed to impose himself on the match and was full of praise for his opponent after the match.

"Kudos to him," Querrey said. "In his service games, there was never a point more than two shots long. It's hard to get into a rhythm, and on my service games, I'd throw in a double-fault and he'd rip one of those continental forehand winners."

Brown will play Canada's Frank Dancevic in the last eight after he defeated French wild card Nicolas Mahut 7-6(5) 6-3.

Mardy Fish, the man Querrey beat in the final at Queen's, never looked in danger of suffering the same fate as he powered into the quarter-finals with a 6-2 6-0 win over India's Somdev Devvarman.

The No. 5 seed, who conceded three games in his first-round win over Michael Russell, capitalised on five of his 14 break point opportunities to reach the last eight at the event for the fourth time.

"It's so much better playing from ahead obviously than playing from behind," Fish said. "With these courts, if you can get a little bit of momentum, if you can hold serve every time then you know you're going to have a shot. I've returned really well the first two matches so I'm happy with that."

Defending champion Rajeev Ram crashed to a second-round exit against South African qualifier Raven Klaasen, going down 5-7 6-1 7-6(3). The win represents the first time that Klaasen, the world No. 417, has won consecutive ATP Tour matches.

Elsewhere in the second round, there were wins for Argentina's Brian Dabul and Belgium's Olivier Rochus.
